High levels of PFAS affect immune, liver functions in cape fear river striped bass
Researchers from North Carolina State University have found elevated levels of 11 per- and polyfluoroalkyl (PFAS) chemicals in the blood of Cape Fear River striped bass. Two of those compounds – perfluorooctane sulfonate (PFOS) and Nafion byproduct 2 – are…
More people and fewer wild fish lead to an omega-3 supply gap
Fully 70 percent of the world’s population doesn’t get what they need of these essential compounds
Generalist diet helps invasive crayfish thrive where it’s introduced

The BBVA Foundation recognizes Carlos Duarte, Terence Hughes and Daniel Pauly for their contributions to understanding and conserving the world’s marine ecosystems
Microplastics from ocean fishing can ‘hide’ in deep sediments
Microplastic pollution in the world’s oceans is a growing problem, and most studies of the issue have focused on land-based sources, such as discarded plastic bags or water bottles. Now, researchers reporting in ACS’ Environmental Science & Technology have linked…

Recreational fishers catching more sharks and rays
Recreational fishers are increasingly targeting sharks and rays, a situation that is causing concern among researchers. A new study by an international team of scientists reveals that recreational catches of these fishes have gradually increased over the last six decades…
‘Blob’ research shows ecological effects that halted fishing and hiked whale entanglements
Unprecedented environmental changes inspire new online tools to better spot them next time
Study connects marine heat wave with spike in whale entanglements
Entanglements of humpback whales in fishing gear along the US West Coast increased dramatically during the 2014 to 2016 marine heat wave known as the ‘warm blob’

The Blue Acceleration: Recent colossal rise in human pressure on ocean quantified
Human pressure on the world’s ocean accelerated sharply at the start of the 21st century and shows no sign of slowing
Turtle tracking reveals key feeding grounds
Loggerhead turtles feed in the same places year after year – meaning key locations should be protected, researchers say. University of Exeter scientists used satellite tracking and “stable isotope ratios” – a chemical signature also used by forensic scientists –…

A model ecosystem fish story
EAST LANSING, Mich. – Have I got a fish story for you. Any angler beginning a yarn like that usually ends up spinning a tall tale, an exaggeration or bald-faced lie. Michigan State University researchers, however, have demonstrated that anglers…

On the edge between science and art: Historical biodiversity data from Japanese ‘gyotaku’
Historical biodiversity data is being obtained from museum specimens, literature, classic monographs and old photographs, yet those sources can be damaged, lost or not completely adequate. That brings us to the need of finding additional, even if non-traditional, sources. Biodiversity…

The carbon footprint of dinner: How ‘green’ are fish sticks?
Popular products generate significant ‘post-catch’ emissions, underscoring the need to measure what happens after fish are caught
Banking on a new community isotope database
NSF-funded IsoBank to serve as a powerful, new resource for researchers who use stable isotope analysis to understand the world

Neither fishing tales nor sailor’s yarn
Collectively, environmental stakeholders are just as smart as scientific experts
The wisdom of crowds: What smart cities can learn from a dead ox and live fish
In 1906, Francis Galton was at a country fair where attendees had the opportunity to guess the weight of a dead ox. Galton took the guesses of 787 fair-goers and found that the average guess was only one pound off…

New study reveals international movements of Atlantic tarpon, need for protection
Results from 18-year study details long-distance migration, habitat preferences
Fisheries management is actually working, global analysis shows
Nearly half of the fish caught worldwide are from stocks that are scientifically monitored and, on average, are increasing in abundance. Effective management appears to be the main reason these stocks are at sustainable levels or successfully rebuilding. That is…
